CAUTION : DO NOT USE EXTERNAL PARTS TO PULL OR LIFT THE IDG. IF YOU DO SO
_______
YOU CAN CAUSE DAMAGE TO THE IDG.
CAUTION : BE CAREFUL TO SUPPORT THE IDG CORRECTLY.
_______
YOU CAN CAUSE DAMAGE TO THE INPUT SEAL IF:
-YOU LIFT THE IDG TOO MUCH
-YOU DO NOT SUPPORT THE IDG SUFFICIENTLY. CAUTION : MAKE SURE YOU INSTALL THE IDG CORRECTLY. IF NOT YOU CAN CAUSE
_______
DAMAGE TO MATING PARTS.
(1)
Remove the protective cover from the IDG interface side of the gearbox.
(2)
Remove the IDG (1) from the plastic bag.
(3)
Install the O-ring (42) in the groove on the IDG splined shaft.
(4)
Install the O-ring (44) in the groove on the IDG (1) pilot diameter.
(5)
Put the IDG (1) on a HOIST - ACCESSORY, IDG R/I FOR CFM56-5 (TMHSD10-20-00) or HOIST - ACCESSORY, IDG R/I FOR CFM56-5 (S387IDG).
(6)
Use the hoisting mechanism to have the IDG level with the mounting pad support. Make sure that none of the weight is on the input shaft.
(7)
Turn the QAD tension bolt (43) to open the QAD ring (46). Align the mark on the QAD ring with the mark on the QAD engine-adapter plate.
(8)
Engage the lugs on the IDG in the openings in the QAD ring. To do this, align the " open-position " mark on the QAD with the opposite mark on the IDG.
(9)

3.44 m.daN).
(10)
Lightly hit the outer edge of the QAD adapter with a softface hammer.
(11)
Do a check of the tension bolt torque. The torque value must not decrease more than 24 lbf.in (0.27 m.daN).
(12)
Do again the procedure until the torque on the tension bolt is between 265 and 305 lbf.in (2.99 and 3.44 m.daN).
(13)
Check the distance between the ring lug and bracket of the QAD ring and bracket. If the distance is less than 0.56 in. (14.2239 mm) minimum,
R (Ref. Fig. 406/TASK 24-21-51-991-303) remove and replace the IDG (Ref. TASK 24-21-51-000-040) and the QAD adapter (Ref. TASK 24-21-41-000-040).
